Transcript of Antibiotic resistance

How does bacteria become resistance
to antibiotics? Overuse of antibiotics (Summer) What antibiotics are: Video http://www.britannica.com/EBchecked/media/83732/Scientists-warn-that-antibiotics-should-not-be-overused Natural selection can influence the effectiveness of the antibiotics by: When antibiotics are taken consistently, they will
effectively destroy the non resistant bacteria leaving the resistant bacteria to survive and replicate (Summer). Natural selection influences the virulence of infectious agents by: This could lead to having none or very little agents for infections.
Already there is some infections that cannot be cured by the antibiotics we have today (Lewis). How national agencies fight antibiotic resistance. By: Cassie Wilson Antibiotic Resistance How international agencies combat antibiotic resistance: Raising awareness about the dangers of improper use of antibiotics and false prescriptions within a country (Stuart). What can the public do to help fight the increased antibiotic resistance? What are antibiotic resistance? Antibiotic resistance arises when an antibiotic can no longer take control to kill the bacterias growth (Stuart). This video explains how Sir Alexander Fleming first found that a petri dish that had been treated by penicillin was still growing bacteria. It also gives examples of some well known antibiotics that some bacteria are resistant to. To enhance an individuals health, antibiotics composed of microbes are used to kill or stop the bacterial growth causing disease (Summer). Works Cited Summer, Cynthia V. "Antibiotics." New Book of Knowledge
(2012): n.pag. Web. 4 Dec 2012. <http://go.grolier.com/>. Bacteria can also become resistant when genes are transferred between two organisms after some time a large number of bacteria become resistant (Cupp 551). not fulfilling the whole amount of time that you should be taking the antibiotics (Summer) Sometimes a gene simply changes in a way that makes it resistant Mutations (Cupp 551). Some bacteria can pump out the antibiotic as soon as it is absorbed into the cell (Summer). Others can change the build of their cell wall making it impossible for the antibiotics to enter (Summer). How does bacteria become resistance to antibiotics? (Continued) Some bacteria can make special molecule that defeat the antibiotic before it kills them (Summer). Some become resistant through a type of evolution Natural Selection (Cupp 551). Cupp, Melanie. "Resistance to Antibiotics". Chicago: World Book

<http://www.tufts.edu/med/apua/> The more the resistant bacteria survive and replicate
the more common they become and the less chance antibiotics will effectively work (Bailey). Bailey, Patricia G. "Antibiotic Resistance." (2012): n.pag. The Canadian Encylopedia. Web. 4

becoming resistant. Numerous organisms form resistance to variety of antibiotics (Lewis). If too many bacteria become resistant to many antibiotics, more
and more people would die from the disease (Bailey). Take antibiotics consistently when it is necessary (Summer)(Stuart). Have good hygiene; wash hands to help prevent the disease (Stuart). To prevent food-borne diseases, cook meat thoroughly and be aware of hygiene when handling food (Stuart).
